The faculty of the Tufts Cummings School of Veterinary Medicine—which treats more than eight thousand older dogs every year—offers this illustrated guide to healthy aging for dogs, with detailed advice on nutrition and caretaking to help your canine age comfortably, contentedly, and well. It includes guidance on evaluating complicated procedures and choosing the best treatment; the cost of caring for an older dog and how to shoulder the burden; identifying and managing cognitive decline; and determining when it is time to let go and how to cope with your loss.
